Question:
| What is required to certify a levee as providing protection from the base flood? |
Answer:
| In order for FEMA to recognize a levee system as providing protection from the base (1-percent annual chance) flood, it must meet, and continue to meet minimum design, operation, and maintenance standards established in Section 65.10 of the National Flood Insurance Program regulations. The design criteria include, but may not be limited to, requirements for freeboard, closure devices, embankment protection, embankment and foundation stability, settlement, and interior drainage. Operation and maintenance plans must also be completed. The operation plan for the levee may include, but is not limited to, procedures for closures, interior drainage systems, and emergency measures. The maintenance plan should detail responsibility and frequency of maintenance necessary to ensure the integrity of the levee system. All items necessary for a levee system to be recognized as providing protection from the 1-percent annual chance flood must be certified by a registered professional engineer. The certification requirement is different if a Federal agency has responsibility for the levee. The Application Certification forms entitled "Revisions to NFIP Map, MT-2," (FEMA Form 81-89 Series) outline the technical data required to recognize a levee as providing protection. |
